* 14 inches: This was the standard size for many 1963 Impalas.
However, to determine the *correct* size for *your* specific 1963 Impala, you need to check:
* Your owner's manual: This is the best source of information.
* The wheels themselves: The size is usually stamped on the wheel.
* The tire sidewall: The tire size (e.g., 7.75-14 or something similar) will indicate the rim diameter.
While 14-inch wheels were common, fitting larger or smaller wheels requires careful consideration of backspacing, offset, and potential rubbing against the body or suspension components. Improperly sized wheels can lead to handling problems, premature tire wear, or damage to your car.
